Posted By Jonathan Breeze Malcolm, I can't give you the details you are requesting, but may be able to provide a pragmatic solution. Are your staff actually aware that they can set up the screen themselves to suit their needs? Just go to "Settings" (in the start menu), click on "Control Panel" and then click on "Accessibility Options". Alternatively, "Settings", "Control Panel", "Display", and "Appearance" will give you a number of scheme options including "Windows Classic Large" and "Windows Classic Extra Large" Your user just has to choose the scheme that best suits their need. Hope this helps.

Posted By Stuart Nagle I belive 'adequate' means adequate for the person using the DSE and software. If they are complaining its too small then I would take it to mean they do not find it adequate for their personal use (i.e size of characters etc). Whilst, as pointed out above, characters can be enlarged under the accessibility options on the computer, I think this will enlarge the page as well so only part of the page is displayed on the screen and perhaps be even more annoying for users who then have to scroll side to side as well as up and down!! I would recommend that a survey of users and operators is undertaken to assess what is needed and for what use to ensure that the equipment provided is 'suitable and sufficient' for those required to use it. Whilst there is a distinction between operators and users, the display screens do not distinguish who those persons are. If all equipment is considered for the task rather than the fact that they are users or operators, I am sure you will get a much better result and satisfaied staff. Stuart

Posted By Jonathan Breeze Kieran & Stuart are of course both right: 1) The size of screen needed will vary for the job in question. For example, CAD operators should not be expected to use standard screens when completing intricate design work. 2) Individuals will also need to be assessed for various eye conditions, to ensure they are provided with appropriate equipment. We have provided several staff members with large screens for this purpose which can also be used to magnify their post for easier reading. I only mentioned the settings because it is a cost free option that many of our users were unaware of until they underwent recent training. I've still not found an answer to your original question though, but I doubt there will be a set standard for legibility as this will vary depending on an individuals eye condition or prescription. Have you tried the Disability Rights Comission website yet? They may be able to provide guidance.

Posted By Nigel Singleton BSc RNIB recomend 14 point in their leaflet about VDU's and visual problems, however this is still dependant on the resolution of the screen. I believe I have seen the figures of between 3 - 5 mm for character height on screen.
